Updated September 5 2014
Deployed new exposure time calculators for all the CFHT instruments: CFHT Instrument ETC
CFHT Dome was modified with vents to aid in flushing thermal turbulence from the optical path of the telescope. In theory, the 'seeing' should improve and approach the levels of free-seeing reported by the MKAM instrument.
The early indications are this is happening.
Early Vented Seeing Data
all sky thermal imaging data of a contrail from a flight over Mauna Kea (animated gif). thermal and visible images side by side.
all sky thermal imaging data reduced for color temperature analysis. a video timelapse of a cloudy night over Mauna kea.
